3 kinds of different thickness wire twisted together patented technology of "3E twist"
3E-twisted structure is at once set stranded conductor of concentric twisted array configuration, by arranging a different wire diameter of three types, densify the twisted wire array. It is possible to reduce the diameter of the conductor configuration, we will strive to improve the conductor characteristic values.Strand of different conductor diameters of this three are arranged in geometric, to minimize voids between the strands, it plays to improve the wire density.Furthermore along with the twisted wire outer diameter of the downsizing, maintaining a stable and high-precision outer diameter, is unprecedented conductor structure in the world cross-section of true circle after twisting. Thus, uniformly brought into close contact with insulation and conductor, homogenized by eliminating random thickness of the insulating material. Such as keep the distance between the shield always uniform, we are working to stabilize the electrical characteristics.
CIS structure in which the air layer and the damper
An air layer as a damper, while improving the high-frequency characteristics by reducing the electrostatic capacity, damping vibrations by its excellent stabilizer effect, adopted Oyaide electrical own cross insulating structure (CIS structure). The basic architecture, employs a coaxial layout in order to make the most of the CIS structure. CIS structure is, the center conductor supported by a point rather than a surface, to minimize the mutual interference between the center conductor and the outer. In addition, the air damper that has been laid out in the interior has been designed in a completely different idea until now. In the approach to conventional vibration, but was a structure that is attenuated by the compound vibrations were internally generated, in the "ACROSS 750 V2", rather than be absorbed by damping vibrations, is the approach of the ideas, such as to open the vibration. In addition, the CIS structure is not only the excellent stabilizer effect, has contributed significantly to the improvement of the electrical characteristics. Since it is provided an air layer between the shield, creating a highly effective to a significant reduction of the electrostatic capacitance. The insulating material that make up the CIS structure, using a high molecular polyolefin exhibits an extremely low value of the dielectric constant is 1/4 as compared with the PVC. These ingenious structure and material, "ACROSS 750 V2" is unrivaled agile response, we stress-free space representation stand out.
ELEC electrical tradition of audio-only halogen-free sheath
Adopts the audio-only halogen-free sheath of Oyaide electrical tradition in exterior sheath, chose Beluga color of refined and elegant finish (Caviar Black). And discomfort without matching to any audio system. Marking the "ACROSS750 V2" "102SSC" to sheath engraved, clearly the V2 model.
ACROSS750 RR V2 dedicated rhodium-plated RCA plug
What you need in order to exert full of originality the potential of the cable to the maximum extent, it is an excellent terminal RCA plug. The RCA plug of "ACROSS750 RR V2", wearing the original exclusive goods rhodium-plated brass pipe-like contact. ACROSS 750 RCA plug that has been specially designed to give a unique identity to the RR (SRR-8: non-single article for sale). The material of the metal part, has adopted a clear brass of the European RoHS directive. Center pin has adopted a tube structure in order to ensure the transmission area of the signal. In addition, all of the contact part, prevents the corrosion of contacts subjected to a rhodium plating of 0.5μ thickness, to maximize the potential possessed by the ACROSS 750. Further, the inner insulating material, employs a low dielectric constant PTFE, aims to reduce transmission loss. Also to the outline of the outer shell, craftsmanship Oyaide electricity has been reflected. Carefully cut one by one by the NC machine training is carried out, precisely then chopped the knurled, chrome plating have been made as well as the camera lens to the finish. The RCA plug is, until the precision machining from member procurement, all have been made in Japan. Unwavering confidence in the quality. Pride is also referred to as "Made in Japan" here is, has been alive.
Using the acoustic dedicated solder "SS-47"
Plug and cable is soldered at the acoustic-only lead-free silver solder "SS-47". Normal solder purity of the tin from the cost is 99.9% (3N) degree. "SS-47" further discharge the impurities increase the purity to the limit, adopt a high-purity tin that indeed 99.993% (4N) or more. Further improvement of the electric conductivity, are designed to prevent leaching of solder, was blended silver, copper. Moreover, the case of normal alloy solder, silver mixing ratio of is from 3 to 3.5 percent, but "SS-47" is an amazing unsparingly put the amount of 4.7%. In addition, 1.7% compounded the next in high conductivity copper of silver among metals. Conductivity by this compounding ratio is dramatically improved, it succeeded in setting the eutectic point 217 degrees. Of course, the blending ratio of these, it has not determined only by numerical data and workability. To hit the solder and the inscription for the audio, the sound quality is considered to be appropriate to the highest priority. I was born that "SS-47" of the many times that there is no hearing test a proto model of a variety of blending ratio.
